Liners and backups

IMC has everything you will ever need in the way of single-use crucibles or 'liners', whether they are made of silica, alumina or zircon. The liners, which you replace after every use, are inserted in a re-usable backup crucible.

Determining the materials and the sizes of your crucibles is not the easiest task. Make sure you contact IMC for assistance.
